IMPROVEMENT IN APPARATUS FOR CHARGING GAS;RETORTSI x Specification `t`ornl1ing part of Letters Patent N o. Ylldoffll, dated July 8, 1873 application filed May 14, 1873.

To all whom 'it may concern frame a endwise. Upon the casing cor bands Be it known that I, ALONZO F. HAVENS, d are bearings IL for the shaft 7c, thatis proof Brooklyn, in the county of Kings and State vided with cranks Z extending to the lungeof New York,` have invented an Improvement in Gas-Retort Chargers, of which the following is a specieation:

erging-scoops for gas-retorts have been made lfor delivering the contents into the retort by drawing aside a divided segmental the length ofthe retort, orirx shorter sections. When the charger is in position for receiving the coal the ends of the folding bottom s rest upon a ledge, u, or part ofthe frame a, and also upon the pins t', and in this' position the charger is inserted into the retort. The end of the frame a', coming into contact with the wise of the scoop, and attached to arms that are employed for lifting up the central portion of the hinged bottom, so as to draw in the edges and allow the coal to be delivered oli' the leaves in their inclined positions toward the angles of the retort, so as to e 'more easily and evenly spread upon the ott' the ledge u, and brings the notches t that there are in the edges of such leaves over the pins 1I, so that the outer edges of the folding' bottom drop, and, by partially revolving the shaft It, the folded bottom s is raised bodily the coal 1s delivered in the center of the reort.

In the drawing, Figure l is a plan of the said charging apparatus. Fig. 2 shows the same sectionally, as in a retort, and containing the-charge; and Fig. 3 is a section with the hinged bottom raised and the coal discharged.

lhe frame a is of suitable size, and either slides or runs upon Wheelsb. W'hen in the retort this frame is supported by the bottoni, and when out of the retort it rests upon suitable tracks or Ways that can be moved along from one retort to the other. The tracks or ways may have rollers near the retort, upon which the liame a rolls. These devices do not require further description.

e casing of the charger is made of the sheet-metal sides c, united at their upper edges delivered upon the bottom.

There may be a crank-arm at the outer en d of the shaft lc, and a counter\veiglit, as illusmeans. As the charger is withdrawn from the retort the coal may be spread by a cross-bar at the back end ofthe fra-me a, and, as the movenient is completed, the end motion is given either to the frame a orparts c d ot' the charger, so as to bring the ledge u below the ends ci" the folded bottom and 'open out the said bottom to its place as the shaft legis turned to lower said bottom. lt' the folding bottom is made in sections a cross-bar will be required to each to actin the same Way as the ledge u. rlhe pins i may be drawn back to drop the sary opening through which the coal is intro edges ofthe folding bottom, instead of using duced. At their lower edges the sides c c are connected to the frame a by means of pins i upon the frame a passing through slots in the sheet metal c, so that the frame a can be moved endwise slightly, or the casingc moved in the with a scale that is dilieult to remove. 'By placing rollers upon the case c and the rollers b so that they run in the anglesfof the reinto the position shown in Fig. 3, and the coal i tort these part-s will be kept free of scale, and being constructed. and opera-ting substantially the other portions of scale can be easily brok; 'as set forth.
